Programmable voice and/or video device

0001The invention relates to a programmable speech and / or video device, especially an intercom and / or video equipment to buildings, with a housing having a lead-provided electronic circuit covers, wherein the electronic circuit comprises at least one with at least a part of the conductor paths connected memory programmable device having.

0002From the prior art it is known that in buildings for communication inserted from the front door in the Audio and Video equipment Buildings will. In these systems, enhanced microcontroller-controlled devices used. The microcontroller used are usually as an integrated semiconductor elements constructed with increasingly ever newer technologies are used.

0003Microcontrollers are increasingly being used by a small amount of memory For example, 2 KB (kilo bytes), 4 KB or 8 KB exhibit. Here are the different types of memory used. While in recent years the OTP technology (One Time Programmable - technology) for the only unique Storing a program used in the microcontroller will be in Future enhanced flash memory technologies are applied. Such Flash microcontroller, up to several 100,000 times with new programs be programmed.

0004In the production of Domophons the flash microcontroller with be programmed appropriate programs and then delivered to the customer. is a reprogramming of the flash microcontroller by the customer currently not possible because the customer himself greater Manipulation of the device would have to make. For a new programming of flash microcontrollers the device generally must be opened and an adapted programming adapter be attached to the microcontroller.

0005is known from the prior art as an additional solution, the application of Known Headers or sockets on the circuit board. About the Power Strips or bushes can reprogram the flash microcontroller by means of a plug will. Disadvantage of these programming options is an uncomfortable Waste handling or generating additional costs due Components such as plugs or sockets.

0006The object of the invention to provide a programmable voice and / or video device indicate in which program changes without opening the housing are easy to carry out. In addition to the inventive programmable Speech and / or video equipment cost, that is, without considerable additional expenditure on components over the prior art be manufacturable.

0007The object of the invention is solved by the features of claim 1. Advantageous developments are described in the dependent claims.

0008Accordingly, the housing has at least one opening, through which with the housing closed at least part of the conductor tracks for programming the programmable logic device electrically contactable is. Opening the housing cover is not in programming necessary, so that no unwanted damage to the electronics of the programmed user caused. In addition, handling is clearly improved.

0009To the electronics to supply particularly in the programming voltage, can be prepared by at least one opening through at least one further Part of the conductor tracks to supply the voice and / or video device a voltage source electrically connected for this purpose or be contacted.

0010Additionally or alternatively, a further opening may be provided by through which at least a further part of the conductor tracks for supplying voltage the voice and / or video device to a voltage source electrically connectable or contactable.

0011In order to create a particularly simple type of contact, have the electrical which contact interconnects contact surfaces on the electronic Circuit carrying on board. It may advantageously the Contact areas below the respective housing opening be arranged and with the respective housing opening are substantially aligned. A simple Contact is guaranteed.

0012To accomplish programming with simple measures, can be the conductor tracks or contact areas by the respective housing opening through contact by means of contact elements with a programmer are connected. Also contact elements provided be to the interconnects and the contact surfaces by the respective housing opening therethrough to connect to a voltage source and to this end to contact.

0013According to a preferred embodiment can be the conductor tracks or the contact surfaces by the respective housing aperture by means of contact elements contacting, with a programming and power supply unit are connected. By providing a single unit for the supply with operating voltage and at the same time to program the programmable logic Component is further facilitates handling.

0014In this case, the programmer and the programming and power supply unit an adapter unit for connection to a computer unit include. By means of this external computer unit allows the programmable logic Reprogram device particularly comfortable.

0015The purpose computing unit used for this purpose has a storage device, in which the einzuprogrammierende in the programmable logic device Program is stored. The computer unit, a desktop computer, portable notebook computer or the like personal computers.

0016To ensure a reliable contact, exhibit according to an advantageous Configuration, the contact elements electrically conductive needle and / or Spring contacts or the like, an electronically conductive connection to the Contact surfaces producing Contacts.

0017can advantageously, in an alternative embodiment, such set contacts in the introduction in the respective housing openings in these. This is a desirable during programming secure ensures contact, so that the data stream and / or the power supply not be interrupted. To this end, the contact elements fit in the housing openings substantially through be defined frictional forces, in alternative or additional training Fixing means for fixing the contact elements in the respective housing openings provided on the contact elements and / or the housing openings could be.

0018By programming the programmable logic device can the functionality of voice and / or video device in accordance with the Change programmed program easily.

0019To the visual appearance of the speech and / or video device not to change, the mindestes an opening and / or the at least one can further opening at the rear side remote from the user of the housing be arranged. Since reprogramming is relatively rare make, can also be a possibly necessary disassembly of the speech and / or video device are taken from a building wall in purchasing.

0020The described programming method can be used for different devices a Speech and / video system are carried out, the contact openings own in the housing. This can also be so-called video stations or his intercom places without handset.

0021The invention is based on a preferred embodiment explained in more detail with reference to the accompanying drawings.
